The column of the desk stand comprises a support 37 surrounded by a tubular spacing member 38. Thev support 37 has its ends tip-turned and provided with openings. rlhe upper end ot the support 37 is tastened to a mounting 81 tor the transmitter (not shown) by means of screws 80. This transmitter mounting 81 is provided with an embossed portion oi sutiicient diameter to receive the tubular member The opening in the lower end oit' the support 37 is threaded so that the screw 39 inserted through the opening 72 ot' the column socket can clamp the support and tubular member ,S58 to the socket. A split wire ring 40 is placed around the bolt 39 to prevent the bolt from dropping out or' the socket when the bolt is uil-screwed trom the support 87. Atthe upper portion ot the support 37 there is pivotally mounted a well known form of switch hook 41 to which a rod 43 is secured. This rod moves in a vertical block ot insulation 78, carried by the support. 37, and is surrounded by a spiral spring 43, which tends to move the switch hook with its rod 42 upward when the receiver is removed from its switch hook. A switch hook spring 44 is secured to the block of insulation 78 by means ot screws 48 and is movable sidewise under the control ot the roller 47 carried by rod 42 in its vertical reciprocating movement. At the eXtreme lower portion of the support, there is secured a second block o1c insulation in an opening ot which there is. secured a rod 45 termina-ting at its upper end in a contact engaged by spring 44. and its lower end extends through the insulation hushed opening 4G ot the column socket to engage thel spring 32 ot t-he terminal rack. lt will thus be seen that when the receiver is removed from the switch hook, the spring 43 forces the rod 42 and its roller 47 upward, permitting the spring 44 to engage the contact ot' rod 45.

In Fig. 7 there is shown a modied :t'orm otterminal rack generally designated 82. This rack is oi the same length as that shown in Fig. 3, and is also provided with openings by which it is screwed to the horizontal portions 21 of the bracket arms. rThis rack is provided with termina-l connections 84 85 and 8G. and with a cut-out portion 83 to permit adjustment ol the screw 39. in this modification it will be noted that spring 32 has been omitted. and it will therefore be necessary that a .Flexible conductor connects the rod 45 lwith the terminal 86.

ln assembling this desk stand the column socket is inserted into the opening ot the base 10, so that the key 2O ot' the socket engages the notch in the` base. The bracket 18 is then threaded over the column socket 11, with the key 2() positioned in its notch 19. The socket. nut 26 is then secured onto the column socket to clamp the column. socket, bracket and base together. rthe support 87 is inserted into the tubular member 38 with the switch hook 41 resting in the notch in the upper portion of the tubular member 88. The column when thus assembled is inserted into the column socket with the notch in the lower portion ot' the tubular member 38 engaging the key 20. The. screw 39 is now inserted through the opening 72 ot the column socket to clamp the vcolumn to the base. The terminal rack or block and induction coil are then secured to the bracket 18 by means oi' screws 29 and 34. The dial impulse sender 17 is placed on the raised portion 15 of the base with the lugs thereof` extending through the opening ot the base. rlhe clamping ring 16 is then inserted'in the lower side ot the base and given a clockwise movement by means of the handles 48 so that the cam surfaces engage the lugs of the dial impulse sender to securely clamp it to the base. rlhe various conductors can then be atlixed to the binding postsand the cover plate 74 secured to the bracket 18 by means ot' screws 76. it will be notedy that theresilience ot the bracket arms cause the base cover to be held securely in position and prevents the holding screws 76 from working loose in service.

lWhen this desk stand is in service, an inspection of the mechanism contained in the upright tube 38, can be readily done by simply loosening screw 39 a` sutiicient amount to release inner support 37, and disconnecting cord terminal connections trom the terminals in the base 10, after which the upright portions 87 and 38 can be entirely removed.

Referring, to Fig. 87 there is shown the desk stand with the apparatus ot the base in substantially the sameposition as shown in Fig. 1. The conductors 13 and 14 coniprising the desk stand cord .are provided at their ends with pin terminals to engage the pin sockets 30. One pin socketis conductively connected with the screw 50 and Aby means ot' a spade terminal. Connection is then made Athrough conductor 51 to the impulse springs 52 ot the dialimpulse sender. The other conductor 13 by means ot its pin terminal and socketterminal 30 which is connected to the spring 32,` connectsl with rod 45, and when the roller 47 controlled by the switch hook is elevated` contact is made benected with the screws `81 ofthe terminaly rack, conductor 56 isfconnected withv conductor 57 which in` turn leads tol theiinpuise springs 52.

Cil

It will be noted that the impulse'sender is provided with shunt springs 58. These springs as is well known arecontrolled by a bushing 59 which permits them to engage eachother when the dial sender is in an ottv normal position, that is, when it is transA mitting impulses. The springs 58, .when closed, complete a shunt circuit around the transmitter from. the impulse springs 52 to springs 58, conductor 6 0, and by means o't the spade terminal engaged by the screw 3l and the socket terminal 30, its conductor 6l) is connected to conductor 6l, and conductor 6l in turn is connected to spring 44 leading to the other side ol the impulse'springs. The receiver 62 is connected to the secondary winding 63 of the induction coil 33, through the socket terminals 35.

lt will thus be seen that a desk stand with an oset column and with a simple arrangement of the supporting means for the termig nal rack, induction coil and dial impulse sender and in which all parts are readily accessible has been provided.
